On June 17, 2024, the Standardization Administration of China (SAC) published seven compulsory standards proposals on minimum allowable values of energy efficiency and energy efficiency grades for public comments on official initiation. All these 7 standard proposals are raised by SAC who will then mandate SAC/TC20 (Energy Fundamentals and Management) to carry out the rest of the development work. Meanwhile, the China National Institute of Standardization will be in charge of translating these standards to English once it is finished, which means that both Chinese and English versions of the standards will be available. Below is a brief introduction to all seven standard proposals:

Minimum allowable values of energy efficiency and energy efficiency grades for crystalline silicon photovoltaic modules and photovoltaic inverters

The standard specifies the energy efficiency limit value, energy efficiency grades, test method and technical requirements of crystalline silicon photovoltaic modules and photovoltaic inverters. The standard applies to monocrystalline silicon photovoltaic modules and polycrystalline silicon photovoltaic modules, as well as photovoltaic inverters for photovoltaic power stations. The main technical contents will include scope, normative reference documents, terms and definitions, energy efficiency grades, minimum allowable values of energy efficiency, and testing methods.

Minimum allowable values of energy efficiency and energy efficiency grades for data storage devices

The standard aims to help related data storage equipment products to improve energy efficiency, and further unify the energy consumption test methods of related products and equipment to maintain the consistency of test results data. This standard will specify energy efficiency test methods and energy efficiency grade evaluation of storage devices in data centers. There are three energy efficiency indicators: IOPS/W, GB/W, and additional points of energy saving performance. The main technical contents will include terms and definitions, abbreviations, technical requirements (grades and minimum allowable values), testing and calculation methods, testing requirements (testing environment requirements, testing instruments and equipment requirements, data storage device setup requirements, testing steps).

Minimum allowable values of the energy efficiency and energy efficiency grades for dehumidifiers

According to the statistics published by SAC, the purchase of dehumidifiers will continue to grow in China, which necessitates efforts to promote the energy efficiency of this product. The standard specifies the minimum allowable values of the energy efficiency, energy efficiency grades, energy efficiency calculation and testing methods. The standard applies to dehumidifiers that use vapor-compression cycle refrigeration for dehumidification.

Minimum allowable values of energy efficiency and energy efficiency grades for floor cleaning appliances

This standard specifies the minimum allowable values of energy efficiency, energy efficiency grades and energy efficiency testing methods for floor cleaning appliances. This standard applies to the test and evaluation of energy efficiency of AC or DC-powered vacuum cleaners and cleaning robots with a rated voltage of not more than 250V in a single phase and used by non-professionals at homes, in shops and similar places such as schools. This standard does not apply to vehicle-mounted vacuum cleaners, vacuum cleaners specially used for cleaning clothes and other special purposes, water-suction vacuum cleaners, floor/carpet cleaners, floor washers, vacuuming floor polishing machines, water-suction cleaning robots, industrial vacuum cleaners and cleaning robots.

Minimum allowable values of energy efficiency and energy efficiency grades for centrifugal pump units for fresh water

This standard specifies the minimum allowable values of energy efficiency, energy efficiency grades and energy efficiency testing methods of centrifugal pump units for fresh water. This standard applies to  single-stage and single-suction centrifugal pumps, single-stage and double-suction centrifugal pumps, inline centrifugal pumps, multistage centrifugal pumps, and light multi-stage centrifugal pumps. This document does not apply to non-metallic pumps and seal-less rotodynamic pumps.

Minimum allowable values of energy efficiency and energy efficiency grades for fiber lasers

This standard specifies the energy efficiency grades, minimum allowable values of energy efficiency, energy-saving evaluation value and testing method of fiber lasers. This standard applies to fiber lasers with rated power ≤10KW. The main technical contents will include terms and definitions, technical requirements (energy efficiency grades, minimum allowable values), and testing methods.

Minimum allowable values of the energy efficiency and energy efficiency grades for medical, laboratory and similar refrigerating appliance

This standard specifies the minimum allowable values of energy efficiency, energy efficiency grades, energy efficiency calculation and testing methods for refrigerators for medical, laboratory and similar purposes.
